Seat device

Abstract

A seat device includes a cushion portion configured to elastically support a seated person and a seat frame configured to support the cushion portion. The cushion portion includes a plurality of divided cushions divided in a seat width direction. The plurality of divided cushions each include a seat pad a seat cover that individually covers each seat pad, and a resin member that is engaged with at least one of the seat cover or the seat pad and is thus individually integrated with the seat pad covered by the seat cover. The resin member includes a snap-fit structure fixed to the seat frame by inserting from a seat front side to a seat back side.

What is claimed is: 
     
       1. A seat device comprising:
 a cushion portion configured to elastically support a seated person; and 
 a seat frame configured to support the cushion portion, 
 wherein the cushion portion includes a plurality of divided cushions divided in a seat width direction, the plurality of divided cushions including a main portion that forms a central portion in the seat width direction and two side portions that sandwich the main portion in the width direction, and 
 each of the main portion and the two side portions includes:
 a seat pad; 
 a seat cover that individually covers the seat pad; and 
 a resin member that is engaged with at least one of the seat cover or the seat pad and is thus individually integrated with the seat pad covered by the seat cover, the resin member including a plurality of snap-fit structures fixed to the seat frame by inserting from a seat front side to a seat back side, 
 
 wherein the seat frame includes a side frame extending along a seat length direction, 
 the plurality of snap-fit structures included in each of the two side portions are provided along the seat length direction in which the side frame extends, and at least one of the plurality of snap-fit structures included in each of the two side portions is staggered in the seat width direction, and 
 each of the plurality of snap-fit structures included in each of the two side portions includes a clip integrally fixed to the resin member and configured to be inserted into a clip fitting hole from the seat front side to the seat back side, the clip fitting hole being provided in the side frame, 
 the clip is elastically deformable such that the clip passes through the clip fitting hole and engages with a peripheral edge of the clip fitting hole thereby prevent separating between the clip and the side frame. 
 
     
     
       2. The seat device according to  claim 1 , wherein the resin member in each of the two side portions further includes a side abutment portion configured to be abutted against the side frame of the seat frame from a seat width direction inner side. 
     
     
       3. The seat device according to  claim 1 , wherein the snap-fit structures in each of the two side portions further includes:
 a hook portion that is disposed on a seat width direction inner side of the clip and configured to be integrally snap-fitted to the seat frame so as to be hooked thereon from the seat width direction inner side as the clip is inserted into the clip fitting hole. 
 
     
     
       4. The seat device according to  claim 1 , wherein the resin member includes a cover fixing groove configured to fix an end of the seat cover by inserting a fastener, which is coupled to the end, from the seat back side. 
     
     
       5. The seat device according to  claim 1 , wherein the side frame includes a plurality of brackets, and the clip fitting hole is provided in each of the plurality of brackets,
 at least one of the plurality of brackets extends outward from the side frame in the seat width direction and a rest of the plurality of brackets extends inward from the side frame in the seat width direction, such that the clip fitting hole provided in the at least one of the plurality of brackets is staggered in the seat width direction from the clip fitting hole provided in the rest of the plurality of brackets. 
 
     
     
       6. The seat device according to  claim 1 , wherein the clip engages only with the peripheral edge of the clip fitting hole. 
     
     
       7. The seat device according to  claim 1 , wherein the at least one of the plurality of snap-fit structures included in each of the two side portions is staggered in the seat width direction, from a rest of the plurality of snap-fit structures included in each of the two side portions.
